•
Choose a location from which
the sensor can “see” all the paths
of movement.
•
The sensor may be wall or ceiling
mounted.
•
As distance from the sensor
increases, it will take more move-
ment to be detected. For instance,
at 10 feet, a half step will be
enough, while at 40 feet several
steps will be necessary.
How large an area does
Stealth detect?
The standard lens detection pattern
extends out 50 feet and is 110º wide.
The sensor may be swiveled in any
direction to cover the area desired.
Always keep the sensor level to
insure full coverage. To reduce
coverage tilt the sensor down.
Stealth STL110 comes with a
standard “Double Look Down”
Lens. This lens has one “Look Out”
zone and two “Look Down” zones,
for excellent detection both at long
and close range.
The Long Range model STL110LRL
provides a long, narrow protection
zone for alleys and along buildings.
How does the LED Detection
Indicator work?
The red LED above the lens shows
the logic state of the sensor. If the
sensor is set for night only opera-
tion, the LED will go on for daytime
detections without turning on the
lights. At night, the LED will be on
all the time, except during detections
(at which time the controlled lights
will go on). At night, the LED serves
as a deterrent indicating a security
device in operation.
